Exocrine pancreatic insufficiency (also called EPI) is a medical condition in which the pancreas of the affected German Shepherd Dog (GSD) stops producing enough digestive enzymes to digest food normally in its small intestine.

EPI in the German Shepherd can result from primary pancreatic disease or several other diseases that interfere with the correct production of enzymes by the pancreas or of activation of the enzymes in the intestine.

What is the pancreas and EPI? And what does this have to do with my own personal German Shepherd?

Briefly: the "exocrine" part of the pancreas is responsible for producing the enzymes we all use to digest our food correctly. Without adequate production of these particular enzymes your German Shepherd cannot digest its food properly either.

If your German Shepherd can't digest it's food, it will not be able to absorb all the food's nutrients properly. Keep in mind that Exocrine Pancreatic Insufficiency can be potentially life threatening, especially in its acute form. However, it often responds well to ongoing and daily treatments when diagnosed and treated with the proper drugs.

Typically, the exocrine functions of the pancreas can malfunction in one of two ways. First, in acute pancreatitis, the dog's pancreas becomes inflamed, causing vomiting and loss of appetite with resulting dehydration. This requires immediate veterinary attention.

Secondly, a previously healthy German Shepherd may begin to exhibit some or all of the following symptoms: excessive water-drinking, ravenous appetite and very soft "cow patty" stools. This is indeed a big tell. No matter how much the dog eats, it will be hungry soon after and will soon begin to lose weight. Typically, exocrine pancreatic insufficiency in the GSD is presented in young adult dogs between 1 to 5 years of age.

The diagnosis of EPI needs to be confirmed by use of laboratory tests. Diarrhea and foul smelling feces due to high fat content results and because all the food ingredients are not being digested completely the German Shepherd will quickly become malnourished.

Signs of Exocrine Pancreatic Insufficiency in the GSD:

? Diarrhea and foul smelling "cow patty" feces.

? Increased gut sounds.

? Excessive water-drinking.

? Weight loss.

? Signs of nutritional deficiency (ex. dry and brittle hair, anemia)

? Ravenous appetite.

Treatment of Exocrine Pancreatic Insufficiency in the GSD:

Treatment of Exocrine Pancreatic Insufficiency often involves the use of replacement pancreatic enzymes. These are given orally to your German Shepherd. Occasionally oral antibiotics may be needed as well. Most often, these EPI products are given in powder form or as crushed tablets, then mixed with the food and left on it for about 30 minutes at room temperature before feeding takes place.

Recommended diet to deal with EPI:

? Feed several small meals daily (at least 3 or more)

? Feed a highly digestible, palatable, complete ration. Consult you veterinarian

? Ideal diet for a dog with EPI : low fiber, low in fat, low excess carbohydrates

Keep in mind, once diagnosed, this treatment is a lifelong commitment for you and your German Shepherd. It may be possible to regulate the condition of Exocrine Pancreatic Insufficiency in the German Shepherd Dogs who are not so severely affected by feeding a very bland low-fat, low-fiber diet and adding an over-the-counter enzyme supplement.

For the more severely affected German Shepherd a more serious regime is required. If EPI enzyme supplementation is stopped for any reason then all the unpleasant symptoms will recur in your dog - and very soon. Oftentimes the German Shepherds response to therapy can be seen within a week or so of starting treatment.

The owner of a German Shepherd diagnosed with Exocrine Pancreatic Insufficiency needs to be very attentive to their GSD's overall condition. After figuring out the correct amount of enzyme(s) needed to produce relatively normal stools and to stop weight loss, the GSD owner can usually feed enough food to help the dog regain lost weight. Relapses are always possible and are shown either in the return of diarrhea or in resumed weight loss.

The dogs owner will have to watch carefully for any of these returning symptoms. Generally speaking, as long as the German Shepherd owner is vigilant in maintaining the diet and enzyme supplements needed by the Exocrine Pancreatic Insufficiency patient, then the dog with Exocrine Pancreatic Insufficiency can live a happy and relatively normal life.
